SGSN
Emulator
The SGSN emulator system is a
cost-effective testing system that provides the user the means to
perform advanced traffic tests for the performance evaluation of the
Gn interface. It simulates the Service GPRS Support Node (SGSN) node
by generating signaling and data traffic, over the Gn interface,
towards the Gateway GPRS Support Node (GGSN) under test.
